Dayco Poly-V Belt 5PK0875
The Dayco Poly-V Belt represents the evolution of serpentine belt technology, building on Dayco’s pioneering work that introduced the first multirib belt for the Ford Mustang in 1979. This premium quality belt continues to set the industry standard with its advanced engineering and superior performance characteristics.
Key Features
- Multi-Rib Design: The five-rib configuration provides superior belt-to-pulley contact, significantly reducing slippage compared to conventional V-belts
- Enhanced Flexibility: Grooved design delivers flexural stress relief for improved flexibility during both normal and backside bending operations
- Controlled Load Management: Multiple ribs eliminate matching requirements and allow for controlled slippage during overload conditions, such as A/C compressor engagement
- Environmental Resistance: Engineered to resist dust and splash-induced slip through its specialized groove pattern
Construction & Materials
- EPDM Compound Construction: Built with high-grade EPDM (Ethylene Propylene Diene Monomer) compounds for exceptional heat resistance
- Aramid Reinforcement: Features aramid-reinforced construction for enhanced durability and load-carrying capability
- Rubber Impregnated Fabric Backing: Dayco’s superior manufacturing technology incorporates rubber-impregnated fabric backing to maximize load capacity while minimizing operational noise
- Specially Treated Cords: Internal cords are saturated with proprietary treatments ensuring dimensional stability and consistent length throughout the belt’s service life
Performance Benefits
- Heavy-Duty Construction: Engineered to meet the demanding requirements of modern diesel and high-output petrol engines
- Stretch Resistance: Specially treated internal cords resist stretching, maintaining critical drive system geometry
- Temperature Resilience: Designed to withstand extreme under-hood temperatures and harsh operating environments
- Noise Reduction: Advanced manufacturing process minimizes belt noise often associated with competitive products
Applications
This belt is designed for specific vehicle applications and should be matched to your vehicle’s requirements. The 5PK designation indicates a 5-rib configuration with K-section profile, suitable for accessory drive systems in automotive applications.
